Vasaka
Sanskrit: Vasa
Justicia adhatoda
A shrub whose leaves and flowers appear across classical Ayurveda and Indian household traditions in preparations linked with the breath and the chest. It is one of the most familiar respiratory herbs in the classical repertoire and forms the base of several well-known syrups. Traditional use is supportive and short-term, never a substitute for asthma or infection treatment.

- People with a bleeding tendency
- People taking regular respiratory medicines, without guidance
Medicine interactions

- Caution with blood-thinning medicines

Quality and buying guidance
Check for Adhatoda vasica or Justicia adhatoda on the label. Ready-made syrups vary widely in sugar content and may include added ingredients, so read the full list if you are diabetic or buying for a child. Dried leaf should be greenish and aromatic rather than brown and dusty.
